Abstract:
We construct a Lagrangian describing the low-frequency dynamics of a system with spontaneously broken phase and translational symmetry (a supersolid). Using the principle of stationary action, we obtain the hydrodynamic equations for the considered system. We give a relativistic generalization of the obtained equations of motion in terms of the Gibbs thermodynamic potential density.
Keywords:
Lagrangian, hydrodynamic equation, superfluidity, lattice, equation of motion, relativistic invariance.
